Dual-Fuel Flexibility and Performance
With Preferred’s SPEC COM Burners and fuel blending technology. Preferred’s Combusion crew continues to push the boundaries of performance and flexibility in industrial combustion systems. A recent project involved outfitting two (2) Superior 1400 HP firetube boilers with Preferred’s advanced low NOx SPEC COM burners and gas blending skids. Each boiler is rated for approximately 48,300 lb/hr of […]
Combustion Solutions for Ultra-Low NOx — A Custom Application
At Preferred Utilities, Combustion Crew continues to deliver advanced combustion solutions tailored for specialty and industrial applications. Recently, a customer approached us with a challenge: their SCR (Selective Catalytic Reduction) system required flue gas temperatures of 700°F to function effectively, but their Thermal Oxidizer was only producing 200°F. Without proper temperature elevation, the ammonia injection process would not […]
Foreign Material Exclusion (FME) Keeps Things Where They Belong
Effective Foreign Material Exclusion (FME) is essential to successful maintenance and outage planning at both boiling water reactor (BWR) and pressurized water reactor (PWR) nuclear plants. Keeping things out of where they shouldn’t be is just as important as putting the right things in the right spot! Tools, debris, and other foreign materials don’t belong in sensitive reactor […]
Reintroducing the Draft Regulator with Linear Actuator: A Legacy Product Backed by Preferred
Following our acquisition of Hays Cleveland, we are pleased to reintroduce the first updated product in the Hays line: the Draft Regulator with Linear Actuator. This unit is a direct replacement for the Hays Cleveland R-9502-1012, combining draft control, sensor, and actuator into one compact, proven solution. And now, it’s backed by Preferred’s 105 years of industry experience […]
Burner Management Series V: Common Flame Detection Methods:
Knowing when a flame is present in a boiler furnace is a fundamental safety function of the burner management system. If a flame is present and the BMS does not detect it, there will be nuisance trips and the boiler cannot operate reliably. Alternatively, if the flame detection is too sensitive and does not recognize when there has […]
105 Years of American Ingenuity: The Legacy of Preferred Utilities
105 years of American engineering and manufacturing.As others have taken American manufacturing overseas or across borders, Preferred made deliberate efforts to keep our manufacturing in the states, and even further, to source American. Part of this commitment was driven by global supply chain realities especially in the past 5 years, but much of it came down to principle. […]
Why Nuclear Maintenance Equipment Requires a Single-Source Solution
We’re pleased to share our recent article in Power Magazine by Steve Mitchell – Wednesday, July 2nd, 2025 There is no room for missteps, miscommunication, or misunderstandings when it comes to nuclear maintenance. It demands precision, speed, and accountability. The tools and systems used during outages must function flawlessly, because when they don’t, the cost is more than […]
Temporary Reactor Pressure Vessel Cover
Fast and reliable Reactor Pressure Vessel Isolation Safety and efficiency are the two most important factors in every nuclear outage. Reducing outage duration, minimizing radiation exposure, and protecting equipment from damage are absolutely key. These responsibilities require tools that are carefully designed and engineered. That’s what Preferred Engineering delivers with the Temporary Reactor Pressure Vessel Cover (TRPVC). It […]
